There are two organizations in the United State which offer formal, recognized soccer coaching education: the US Soccer Federation (USSF) and the National Soccer Coaches Association of America (NSCAA). The courses on offer by these groups provide coaches with both theory and practical knowledge on how to teach the game. Just like being a good student doesn’t make you a good teacher, being a great player "back in the day" doesn’t necessarily mean you’ll be successful as a coach. Earning a basic USSF license or NSCAA diploma (or both!) will help you learn the right way to structure practices, demonstrate a skill, teach tactics and encourage your players in a positive manner. It will also improve your own confidence and make your experience as a coach more enjoyable.
